Kurz

The standard single-point insertion thermal mass flow meter for industrial gas, with process temperature ratings published for both a moderate-temperature and a high-temperature version.

Use it whenReach for this first for ordinary dry industrial gas in a pipe or duct big enough to insert a probe. It is the default; you should only move off it if the gas is wet, the line is small enough to favor an in-line body, or the duct is large enough that one point will not represent the profile.

The wet-gas version, which Kurz describes as the first thermal mass flow meter engineered specifically for wet gas, condensing gas, and biogas, processing the dry flow signal independently of moisture in the stream.

Use it whenUse it when the gas condenses or carries droplets - digesters, landfill gas recovery, animal feeding operations, wet stacks, and mining. Kurz says plainly on its landfill page that standard thermal meters do not work well in condensing gas, so if there is any chance of moisture, specify the WGF rather than hoping.

A single-point insertion meter designed specifically to monitor aeration air flow in water and wastewater treatment plants.

Use it whenUse it for aeration basin air on a municipal or industrial wastewater plant, especially where the air flow is being trimmed for dissolved-oxygen control. It is the purpose-built choice for that duty; a 454FTB will also measure aeration air but the 410FTB is the one aimed at it.

A multipoint insertion meter that uses up to four sensors for measurement redundancy and to average across the cross-section.

Use it whenUse it in large industrial stacks and ducts where velocity or temperature varies across the opening, or where vibration and stress make a single probe a risk. If you cannot find a straight run long enough to give a single-point meter a clean profile, this is the answer instead of arguing about installation.

The wet-gas version of the multipoint bar, processing the dry flow signal independently of moisture.

Use it whenUse it for wet stacks, condensing gas, and biogas where you also need multipoint averaging - typically a scrubbed stack downstream of wet control equipment.

A multipoint insertion meter that Kurz states is QAL1 certified for use in automated measuring systems for continuous emissions monitoring.

Use it whenUse it when the flow measurement is part of a regulated CEMS and the certification is the deciding factor - combustion and emissions stack duty where an auditor will ask what the meter is approved to. Kurz also lists MCERTS and SIL among its approvals, so confirm the exact certificate you need per model.

An in-line meter built with inlet and outlet piping reducers and expanders, which Kurz says gives exceptional immunity to upstream and downstream flow disturbances from elbows, valves, and line size changes.

Use it whenUse it when the line is short on straight run, or full of elbows, valves and size changes, and you need the meter to shrug that off. It is the answer to 'we have no room for ten diameters upstream.'

An in-line meter for applications where flow disturbances or line size changes are not an issue, offered in ten models covering half-inch to four-inch pipe.

Use it whenUse it when the piping is clean and straight and you do not need to pay for the 534FTB's built-in conditioning. Same technology, simpler body, lower cost.

A family of portable thermal air velocity meters. The 2443 is a short rugged probe for traverses in small and medium pipes and ducts; the 2444 is a heavy industrial unit built from multiple sixteen-inch sections that connect to reach further into a duct; the 2445 is the very-high-temperature model aimed at coal-fired stacks and primary and secondary air ducts.

Use it whenPick by how far in you need to reach and how hot it is: 2443 for industrial ventilation and modest duct sizes, 2444 when you need extension sections for a big duct, 2445 when the gas is hot enough that the other two are out. This is the family for balancing, troubleshooting, and proving a permanent meter.

A miniature, low-cost thermal air velocity meter that Kurz positions for velocity measurements tied to EPA and OSHA emission rules across a variety of vapor emission sources.

Use it whenUse it when someone needs a defensible velocity number at a hood, vent, or fugitive-emission point and a full traverse kit is overkill. It is the one to hand an EHS technician.

A microprocessor transmitter that powers and reads up to sixteen independent sensing points and reports a grand average of flow and temperature.

Use it whenUse it on a large duct with an unstable velocity profile and a wide temperature spread, where you want one averaged number out of many points. This is the piece that turns a scatter of sensing locations into a usable duct flow reading.

A flow computer offered in five models that combines temperature and flow measurement, closed-loop flow control, totalization, alarms, input and output calibration, and data acquisition for up to twenty-two sensors.

Use it whenUse it when the job is not just to read flow but to control it, totalize it, alarm on it, and log it - and especially when there are many sensors to bring back to one place. It is also the controller inside the isokinetic sampling system below.

A complete system that ties stack flow monitoring, sample capture, and sample flow control together so the sample composition tracks the stack; Kurz offers a wet stack option and states it eliminates under- or over-reporting of gas or particulate constituents.

Use it whenUse it when a sample has to be representative to be defensible - environmental, process, and nuclear sampling. If a lab result is going to a regulator, the sample rate has to follow the stack, and that is what this system does.

A control valve that provides fine control of the sample flow within the sampling system.

Use it whenSpecify it as part of a Series 220 system rather than on its own - it is the final control element the Series 155 computer drives to hold the sample isokinetic.
